From 0d61f879a1f2e6bb37368731a29d5267e1c25195 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Sun, 4 Nov 2012 16:43:44 -0700 Subject: mesa: assert that key->fragprog_inputs_read value isn't too large fragprog_inputs_read is a 12-bit bitfield so check the assigned value. MSVC warns on the assignment. Not easy to fix but let's do a sanity check.
